Dallas Cowboys linebacker Sean Lee is facing surgery on his right big toe.

According to several reports Tuesday night, including one on the team's own website, Lee has ligament damage in his toe that will require surgery and could end his season.

Lee, the team's leading tackler with 58 stops, got hurt in the second half of Sunday's win at Carolina. He was on crutches after the game.

Coach Jason Garrett said Monday that the team was still awaiting results of an MRI on Lee's toe. There was no availability Tuesday when the team had its normal off day.

Dan Connor, a free-agent addition during the offseason, would likely replace Lee in the lineup.
